Alma Libre Dive Center
Cozumel dive centre inside a north-shore beach club, running boats south to the park reefs, with coral and fish identification taught on ordinary dives.
Also known as: Cedar Pass, Cedral, Cedral Pared, Cedral Pass, Cedral Wall, El Paso del Cedral Reef, Mounds of Cedral, Paso de Cedral, Paso El Cedral
Low coral mounds and sand channels on Cozumel's mid coast, a 9-18 m drift for nurse sharks, toadfish and fish crowded into the reef's breaks.
Last updated October 2026
Splendid toadfish are the first thing guides look for at Cedral, wedged into crevices at the foot of the finger coral where the drift begins on flat ground. Spotted drums work the shade nearby and an octopus may be folded into a hole, and guides know the small caves in the sand where big lobster and the odd large green moray sit. The current can run hardest on this stretch, before any structure offers shelter.
Then the reef begins and the fish come with it: grunts and snappers in large schools, packed into the breaks. Every gap is a pocket out of the flow, and the gaps work for a diver too. With a coral mound between you and the current you can wind back and forth across and under the reef, and twenty or thirty minutes over one stretch is realistic. This middle third is where photographers spend most of the dive. The drift finishes over another mound of sand where barracuda hang and turtles feed.
How it feels depends on the water. At the quiet end of its range this is a reef you work at walking pace; on a strong day it is a fast ride over the coral with the group strung out behind the guide. Most operators run Cedral as the second tank of the morning, though as the first dive of the day it tends to be less crowded and better lit for photos.
Along the outer edge the ground falls away into Cedral Wall, past 30 m and in faster water. Reef and wall seldom fit into a single tank, so choose on the boat.
Cedral packs a great many fish into very little relief. The reef is low and broken, and the breaks are the point: each one gives cover from the current, and large numbers of fish congregate in that shelter. Grunts and snappers fill them, green morays are a good bet, and nurse sharks turn up regularly among the mounds.
The Endangered splendid toadfish sits in crevices of the flat opening, found at 12-18 m on a relaxed profile with gas to spare.
It is one of the island's most visited reefs, and groups often drift over it close together.
Eight divers behind one guide, several boats on the same strip and water moving faster than anyone swims make losing the group the likeliest problem. Carry a surface marker, agree the plan on the boat and use the breaks in the reef when you want to stop.
On a second tank nitrox buys minutes: a diver who is good on air can press the no-stop limit here with plenty of gas left.
Cedral reef and wall were rested in February and March in both 2025 and 2026, the months the island is sold for its clearest water, so ask your shop which reefs are resting for your dates.

Gaps in the coral give cover from the current, and large numbers of fish gather in them
They turn up regularly over the sand gaps between the coral mounds
Splendid toadfish are looked for in crevices where the drift begins
Moderate to strong, south to north, from a walking pace reef to a fast ride
Cedral Wall runs along the seaward edge, deeper and faster, and rarely fits the same tank

December to May is the clear-water window. February and March are often reef-rest months here, so check with your shop for your dates.
The standard product is a two tank boat morning, with this reef usually on the second tank. A federal duty is payable per person for each day you dive inside the park; your centre adds it and issues the wristband. Nitrox is an extra and worth the money on this profile.
Operators grade the standard reef from Open Water to Intermediate and none asks for Advanced, and 18 m sits inside an Open Water card. The wall option is pitched at more experienced divers: one operator files it under advanced dives and another says experienced divers may choose it, in faster current and well past the reef's depths. A guide has to supervise every dive in the park.
Summary
Moderate, and the drift sets the level. Being carried along a reef faster than you can swim, in a group of up to eight with other boats working the same strip, is the step up, and losing the group is how the dive goes wrong.

The wall runs along the seaward edge of the same reef, so it is reached from the same boat ride. Two shops list it as a separate dive and one of them files it with the advanced sites, and others sell one Cedral with the wall as an option inside it. Divers who know the reef say you can start on the pass and cut over to the wall, but that has to be arranged before the dive, and one tank rarely holds the bottom time for both. Say which one you want before you get on the boat.
The reef is a 9-18 m dive inside an Open Water card. The wall goes well past that: one operator says it drops to more than 100 ft (30 m), a 2008 magazine describes the dive from about 40 ft to more than 100 ft, and sharks have been seen at 100 to 120 ft off the wall. Operators pitch the wall at more experienced divers and one files it under advanced. The park's rules say nothing about the diver's card, so settle it with your guide and dive your own computer.
Expect moderate to strong, south to north, with a few shops calling it gentle on their quieter days. A divemaster once put it at 3.5 to 4 knots in 2012, but the diver he told had estimated 2, and divers generally overestimate current. Read it as a sign that a strong day exists, and plan for water you cannot swim against.
The reef is named for it. El Cedral is an inland village on Cozumel with a small ruin, a church and a spring fiesta, and anything you read about a fiesta, a ruin or a rodeo there belongs to the village, not to the dive.
